PROBLEM TO BE SOLVED: To provide a new method for ultrasound synthetic imaging capable of improving a method for plane ultrasound synthetic imaging.SOLUTION: A method for ultrasound imaging comprises at least the following steps: a transmission step in which a plurality of ultrasonic waves are transmitted into an imaged region and a set of raw data is acquired by an array 2 of transducers in response to each ultrasonic wave, the ultrasonic waves having different spatial frequency content; a coherence enhancing step in which, for each of a plurality of virtual transmission focal zones in the imaged region, at least one set of coherent data is synthesized from the sets of raw data; and a beamforming step in which, for each of a plurality of locations included in each of the virtual transmission focal zones, an image pixel is computed by beamforming, using the set of coherent data.SELECTED DRAWING: Figure 2 |
